Answer: The first one (12+17)-9=(23-7)+4

Explanation: First add 12 and 17 because it’s in parentheses which will give you 29. Then subtract 9 to get 20. After that, solve the problem on the right side of the equal sign, therefore 23-7 is 16. Lastly, add the 4 to 16 to get 20 which means that this equation is equal because (12+17)-9 does give you the same answer as (23-7)+4 which in conclusion means it’s a true equation.

Find the volume of the prism.

Zigmanuir [339]

Answer:

The correct answer is first option. 270 m³

Step-by-step explanation:

Formula:

Volume of prism = Base area * Height

Area of triangle = bh/2 where b - base and h - height

From the figure we can see that height of prism = 36 m

Base is a right angled triangle with base 5 m and height = 3 m

<u>To find the Base area</u>

Area of triangle = bh/2 = (3 * 5)/2 = 15/2 = 7.5

<u>To find the volume of prism</u>

Volume = Base area * height = 7.5 * 36 = 270 m³

Therefore the correct answer is first option . 270 m³

Answer:

$x = 14.13ft$

Step-by-step explanation:

Given

See attachment for illustration

Required

Find x

To do this, we apply Pythagoras theorem.

From the attachment, the length of the hypotenuse is 16.7ft

While the length of the opposite/adjacent is 8.9ft

Length x is calculated using:

$16.7^2 = 8.9^2 + x^2$

$x^2 = 16.7^2 - 8.9^2$

$x^2 = 199.68$

Take square roots

$x = \sqrt{199.68$

$x = 14.13ft$
